I have a sunstar zx 30 that for the past week everyone has asking if had been rebulbed because it is so hot It hasn't been rebulbed it has 250 hours on the current bulbs.So hot that it feels like it is burning your heels.(I tanned in it last night to see for myself) I noticed the heat in the room too that normally is not bad.I have checked all the fans they are clean & working ,so are the end caps .It is hooked up to a buckbooster to reduce the power going to it because the voltage coming in was to high ,So I don't think it could be high voltage because of the buckbooster .Does anyone know of anything else to check. Also I don't know if this could have anything to do with it but some of the bulbs are burning almost orange at the ends .Any advise would be greatly appreciated

I agree with Neon, mine did that before, Under the bed in the blue box is a FILTER, mine needed to be vaccumed!
I had changed the bulbs, cleaned out the bed and forgot the filter!
and another bed top got so hot it was melting the top! I had 2 cooling fans out!

I agree with NEON. Take it a step further. Turn the bed on and keep checking ALL the cooling fans for proper operation for the entire session. You might have one or more cooling fans turning off after the bed starts.
